4/3+mm Men's O'Neill PSYCHO TECH Chest Zip Fullsuit
Here are all the reasons why this 4/3+mm Men's O'Neill PSYCHO TECH Chest Zip Fullsuit is one seriously warm and dope suit. First, it's made with 100% super stretch TechnoButter 3 neoprene which is so soft and stretchy it's not even funny. Second, it's got sealed seams with a Fluid Seam Weld and Aqua Alpha Solvent Free neoprene lamination for a watertight and leakproof wetsuit. Other features include: a F.U.Z.E. chest zip closure system, TechnoButter 3 Air-Firewall smooth skin outer panels, 0.5mm of extra thickness (which is why there's a + sign in the title of this suit), TechnoButter 3 Air-Firewall lining for a super warm and quick-drying suit without the weight, stitchless seam technology for great range of motion and durability, tough kneepads, super seal cuffs, and a glideskin neck for comfort.
